What is BS EN 61000-4-26:2011?

BS EN 61000-4-26:2011 is a professional technical standard that addresses electromagnetic compatibility (EMC) in electrical and electronic equipment. It is part of the EN 61000 series of standards, which provide guidelines for managing electromagnetic interferences in various environments.

The Purpose of BS EN 61000-4-26:2011

The primary objective of BS EN 61000-4-26:2011 is to ensure that electronic and electrical equipment operates correctly and without disruption in the presence of electromagnetic disturbances. These disturbances could arise from external sources like power lines, radio waves, or other electronic devices.

This standard specifies the test procedures and performance criteria to assess the immunity of equipment to various electromagnetic disturbances. It covers a wide range of issues such as power frequency magnetic fields, voltage dips, short interruptions, and voltage variations.

Key Requirements and Testing Procedures

To meet the requirements of BS EN 61000-4-26:2011, manufacturers need to ensure their equipment can withstand common electromagnetic disturbances. The standard specifies different tests for conducted disturbances, radiated disturbances, and fast transient/burst disturbances.

During testing, equipment is subjected to simulated disturbances to evaluate its immunity. These disturbances are generated using specialized test equipment that can reproduce real-world electromagnetic scenarios. The equipment's performance is assessed based on its ability to function correctly during and after exposure to these disturbances.

Compliance and Benefits

Compliance with BS EN 61000-4-26:2011 ensures that equipment is designed and manufactured to withstand electromagnetic disturbances commonly encountered in various operational environments. By adhering to this standard, manufacturers can enhance the quality and reliability of their products.

For end-users, using equipment that complies with BS EN 61000-4-26:2011 offers several benefits. It reduces the risk of malfunctions or failures due to electromagnetic interference, improves system performance, and promotes compatibility with other devices in the same environment.

In conclusion, BS EN 61000-4-26:2011 is a critical technical standard for managing electromagnetic compatibility in electronic and electrical equipment. Its guidelines and test procedures help ensure the reliable operation of these devices in the presence of various electromagnetic disturbances, ultimately benefiting both manufacturers and end-users.
